Retiring Rep. John Dingell, the longest-serving member of Congress, has served with every president since Dwight Eisenhower — a total of 11 White House occupants starting in 1955.

Smart Politics, a blog by the University of Minnesota’s Humphrey School of Public Affairs, has crunched other numbers dealing with the Michigan Democrat’s storied political career and each are eye-popping. Some examples:

2,448: The number of members Dingell so far has served with in the U.S. House of Representatives. That number will go up when vacancies are filled in Florida, New Jersey and North Carolina during special elections this year.

223: The number of women in Congress that have served with Dingell. Eric Ostermeier, who writes the Smart Politics blog, calculates that Dingell has served with 86% of the 260 women in history who have been elected to the House.

21,571: The number of days Dingell will have served in Congress, when his 29th full term officially ends in January 2015. Ostermeier calculates that Dingell will have served 15,727 of his days in office as a member of the House majority — which comes out to nearly three out of every four days or 73% of the time.

Presumably, Dingell’s days in the House majority were happier times for the lawmaker. The Democrat has made no secret he has not enjoyed his time in the House minority, especially in the current 113th Congress.

“This Congress has been a great disappointment to everyone, members, media, citizens and our country,” Dingell said when announcing his retirement on Monday.
